Hi, I've been searching a lot about bump steer mods you can do to the Tuscan.

I've read about rack spacers, sag arms and flipping the track rod ends on the standard arms.

There was a bump steer kit group buy a few years ago with new track rods that allowed flipping and rack spacers. Anyone know of anything similar these days?

If not then is there anything special that needs to be done to the track rods to flip them? Are they interference fit? Or is it as simple as it sounds?

Cheers all.

What is the rack widths and what exactly do I need to measure?

Any idea what standard ride heights are? My car has nitrons.

Thanks for your help.

Do I need to take the track rod end off to measure or will the length difference be pretty obvious even with the end still on?

Haven't looked at this in a while.

I'm off on holiday for 2 weeks tomorrow however on my return I'm having the following done to my Tuscan.

10mm rack spacers
Move shims to max castor
1 degree negative camber & 0.5mm toe in either side for the front.

Rear is already 1.4 negative camber and 1.5mm toe in either side.

Car is running 235/40 & 255/35 tyres - Rainsports as far as I can remember. I'm also getting the wheels refurbed and straightened if needed - I feel a slight wobble at crusing speeds that feels like an unbalanced wheel, it may just be this.

I might have to play with the harshness of the Nitrons, they feel incredibly stiff - anyone know how many adjustments/clicks they have?

I'll keep you updated.

Rack is spaced, castor adjusted and some camber dialled in.

It's getting there now, feels much better. Going in for a final geo on Friday to hopefully cure everything!

Got the Tuscan back and its much better. It will cruise happily at 100 mph with 1 finger on the wheel, without trying to dark across the road over every bump.

Strange this is that they couldnt dial in enough positive camber on the front, it was maxed out aparently at about 1.4-1.5 degrees negative, I was hoping for 1 degree.

Does anyone know the ideal ride height for these?
